Peter Welch is standing in a field in southern England, armed with a metal detector and a shovel. A patch of farmland, surrounded by other patches of farmland, begs the question: Why search this one? “You’re looking for crop marks, parch marks, circles, unusual features. Anything that doesn’t blend in with the countryside can be evidence of buildings, roads, and other structures from centuries ago.” It’s in these outliers where treasures lie – and it’s Google Earth that gives Peter the bird’s-eye view he needs to find them.
Peter has made thousands of discoveries, many of which were over 300 years old, including fragments of swords, ancient jewelry, even a Roman horseshoe, known as a “hipposandal” – but nothing compares with Peter’s biggest find: a hoard of Saxon coins valued at over £1.5 million pounds.
Peter’s fascination with metal detection began at his parents’ horse-racing yard in 1976, when he used his first metal detector to find old Roman coins and jewelry on the property. He turned his hobby into a full-time gig in 1990, when he founded the Weekend Wanderers Metal Detecting Club. Peter arranges and leads experts and novices alike from around the world on metal-detecting excursions. It’s the biggest club of its kind in the U.K.
Although Peter has been doing this for decades, his success rate of uncovering historic finds has grown since the launch of Google Earth, which helps him research farmlands to search and saves him from relying on outdated aerial photography. In December 2014, Peter noticed a square mark in a field with Google Earth. It was in this area where the Weekend Wanderers discovered the £1.5 million cache of Saxon coins. The coins are now on display in the Buckinghamshire County Museum, by order of the queen’s decree.
While nothing yet matches that discovery in scale, there’s a lot of unexplored land that’s yet to be seen by a metal detectorist. “You never know, we might strike it big again,” Peter says.
“I’m pretty sure it won’t be long.”
